SENTRO GAS SENSOR/TRANSMITTER<br />
SENTRO eModule<br />
FLAMMABLE GASES • POISON RESISTANT CATALYTIC SENSOR<br />
SENTRO eModule utilising a poison resistant catalytic combustion <strong>sensor</strong> to<br />
monitor flammable <strong>gas</strong>es present in the atmosphere. The <strong>sensor</strong> will respond to<br />
most flammable <strong>gas</strong>es and vapours to varying degrees; it is normally calibrated<br />
to methane in terms of %LEL or %volume. Very good sensitivity at low levels of<br />
concentration but not suitable for use above the LEL level. Calibration for other<br />
flammable <strong>gas</strong>es can also be provided.<br />
The relatively large mass of the sensing element assures a long and reliable<br />
operating life with exceptional stability, even in conditions of high vibration.<br />
The natural life of the <strong>sensor</strong> is about five years depending upon the monitoring<br />
conditions and the module can be quickly replaced and serviced at the end of its<br />
operating life.<br />
TX6350.240 Methane 0...100% LEL<br />
Can also be calibrated for other flammable <strong>gas</strong>es to specification<br />
eg. LPG, Propane, Butane, etc.<br />
SENTRO eModule<br />
CARBON DIOXIDE/ METHANE GASES • INFRARED SENSOR<br />
SENTRO eModules with an infrared <strong>sensor</strong> are used for monitoring environmental<br />
concentrations of either carbon dioxide or methane <strong>gas</strong>es.<br />
This <strong>sensor</strong> is highly specific to the selected <strong>gas</strong> and exhibits consistent sensing<br />
accuracy with superior long term stability; so minimising calibration and<br />
maintenance.<br />
The essentially linear response and high sensitivity of the <strong>sensor</strong> means that it<br />
can be calibrated equally well for low <strong>gas</strong> concentrations and high<br />
concentrations up to 100% by volume.<br />
TX6353.242 Methane 0...100% v/v<br />
TX6353.243 Methane 0...100% LEL<br />
TX6353.253 Carbon dioxide 0...2000ppm<br />
GAS SENSING MODULE SETTINGS<br />
Gas sensing modules are normally supplied with preset function data and no<br />
further setting-up will be necessary – SENTRO will immediately recognise the<br />
module and its settings when it is loaded.<br />
Module parameters can also be setup to individual requirements when requested.<br />
Scaling, duty text and setpoint alarm values are pre-programmed.<br />
